Specification of Letters Patent.

Patented Deo. 15, time.

Application led August 28. 1914. Serial No. 359,137.

To @ZZ @from it muy concer/i it known that I, Ifunornicn C. Henson, a citizen of the United States, and a resident ol" Boston, in the county of Sutl'olk and Ntate ot lvlassachusetts, have invented cci tain new and "useful Improvements in 'Vlieeldullers, of which the following is ,a specification.

This invention relates to certain improvements in devices for use in removing wheels7 cams, dy wheels or other rotors from the end of a shaft, axle, spindle or the like, and more particularly to that type in which two members are employed, one of said members being a' apted to engage with the rotor and the other to engage with the axle or other support. In ordinary practice these two mcmbers have threaded engagement with each other and are relatively rotatable about an axis in alinement with the axis of the rlfm" and support. W' ith the device properly in place, relative rotation of the members will produce a steady strain tending to slowly pull the wheel endwise oil' ot' the axle. It often happens that the contacting surfaces have rusted or have become so tightly wedged or stuck thnt `this gradual strain is or' very little effect in securing the desired axial. movement. y

The main object ot my invention is to provide nieruis in combination with said relatively rotatable members for jarring or tapping the parts and thus tend to break the rust or loo; n the wheel so that it may be more easily removed by the gradual and steady strain Aesulting from the aioresnid relative rotati!` of the members.

In carrying ci 1, my inven pn, I provide a slidable member .crably in the loria of a tloating pin coax with the other two mem- A bers and having axial movement in respect thereto. 'l` pin is preferably so ,i with the end ot' the axle so that blows ocnvered to thc outer end oi'f the pin will be communicated directly to said axle. By mounting the pin within one ot' the two members so as to be carried by thc latter, it will be in proper position for use irrespective of such variation in axial position as may be elfe-cted by the relative rot'ation of the two main parts.

Reference is to be had to the accoinpanying drawings in which I have illustrated one practical and satisfactory embodiment of my invention but, as various changes may mounted as to en be made within the scope olE the appended claims without departing from the spirit of my invention, I desire the drawings to be considered in an illustrative rather than in aU limiting sense.

In these drawings: Figure 1, is a longitudinal section through a portion of a wheel puller constructed in accordance with my invention and a portion of a wheel and axle. Fig. i), is an end view of the device shown in Fig. 1. through a slightly niodilied form of screw and loatingpin and, Fig. 4, is a section similar to Fig. "o, but showing a further modification.

In the specific embodiment illustrated in the accompanying drawings, the two main members of the device comprise z cap 10, and a. screw ll, the latter extending through the end wall ot' the cap and having threaded engagement therewith. The specific construction of these two members does not form the important portion of my present invention, r i it is evident that they may be varied widely within the scope of my claims. .\s shown. thc cap 10, interiorly threaded at its open end so as to screw on to the hub 1:2 of a wheel, and is provided with aslot 13, extending lengthwise thereof. Lugs lfl upon opposite sides of the slot are connected by a screw 15 so that by drawing the two lugs together, the interior diameter of tho cap may be slightly reduced or the cap may be more effectively gripped on the hub after having Vbeen screwed onto the latter. In using the device for ren'ioving wheels from vehicles, this specific construction possesses certain advantages in that the cap may be screwed on to the same threads of the hub which ordinari ly receive the usual hub cap. so that by removing the. hub cap the wheel puller cap may be put on in place thereof. In caso the device is to be used for removing cams, ily wheels or other similar members from thc ends ol shafts, spindles or other supports, it is evident that the ineinbcr l0 instead of being in the forni o'l a` cap might bc ol' skeleton Vformation. or might have hooks or other parts for engaging with the element to be removed instead of having screw threads to screw on to the latter.

rllhe screw il, as previously stated, extends through the end or' the cap l0. and is in direct aiineinent with the axle lo which supports thc hub and from which it is de- Fig. 3, is a longitudinal section than the screw and at its inner end may en-l gage with the end of the axle so that by pounding or tapping pin, the force of the blows may be directly transmitted tothe axle.

ln removing a wheel the screw 11 is first tightened up Jso as to apply a strain tending to force the wheel endwise in respect to the axle, and in case sonable amount of force in turning the screw does not pull the wheel endwise, blows may be applied to the outer end of the pin which will jar the parts suiiciently to break the rust er loosen the parts which are stuck or wedged together. As the pin is freely movable endwise through the screw at least for a limited distance, it is evident-that continual pounding on the pin, does not apply any strain to the threads connecting the two relatively rotatable members 10 and l1. As xsoon as the parts are jai-red loose by tapping on-the pin, the screw 1l may again be rotated and further strain applied toward the pulling off of the wheel. The turning of the screw and the tapping on the pin may be carried on alternately orf-simultaneously until the wheel is entirely removed, although ordinarily after the vwheel once has been started, the tapping is -no longer necessary. The pin may be freely removablefrom the screw or may be permanently attached thereto with a limited endwise movement. Preferably the latter construction is employed and this avoids the liability ot' losing or misplacing the pin. Instead oi' providing a special pin the screw may merely have an axial passage through which a short steel rod or other member may act as a plunger, and in place of the ioating pin. In Fig. l, I have shown the pin 17 held in its place by swaging over the ends to for-m heads iii- 18. In Fig. 3, I have shown ,a pin 17EL having separate portions of different diameters and separated bv a shoulder 18a adapted to engage with a corresponding shoulder within the screw llEL so as to limit the endvvise movement of the pin in one direction. In Fig. 4, l have shown a pin 17b having a collar 1S thereon for engagement with a shoulder in screw 11D so as to limit endwise movement oi the screw in the opposite direction. It is oi course evident that any other suitable means may be employed for limiting the extent of on the outer end of thethe application of a rea.

slidably through vwith a rotor, and

the free that as freely removable.
